WINDMILL..

SPECIFICATION forming part of Letters Patent No. 342,736, dated May 25,1886.

Application filed March 8, i886. Serial No. 194,434.

.To @ZZ whom it may concern.-

Beit known that I, JOHN \V. OURRIE, of Solomon City, in the county ofDickinson and State of Kansas, have invented a new and ImprovedWindmill, of which the following is a full, clear, and exactdescription.

My invention relates to windmills, and has for its object to provide aninexpensive, strong, and durable mill, which may readily lo be throwninto and out of gear, and is selfregulating when in gear.

The invention consists in certain novelv features of construction andcombinations of parts of the windmill, all as hereinafter fully r 5described and claimed.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters indicate correspond- 1 ingparts in all the figures. 2'0 Figure lis a vertical sectional sideelevation of the head portion of a windmill made in accordance with myinvention, the windw-heel sails being removed and parts being brokenaway. Fig. 2 is a plan View, partly sectional, and shows in full linesthe relative positions of the wind-wheel shaft and vane when the mill isin gear; and shows in dotted lines the position of the wind-wheel whenthe mill is out of gear, and Fig. o is a vertical 3o sectional elevationtaken at right angles tov the same parts shown in Fig. l.

The head of the mill consists, mainly, of a four-way wrought-ironpipe-coupling, A, commonly known as a cross, opposite wrought- 3 5 irontubes B C,threaded into the screw-necks l 2 of coupling A, and a thirdwrought-iron tube, D, threaded into the screwneck 3 of the coupling andextending at right angles to the tubes B C. The tube C is journaled inthe 4o head-piece e of the mill-towerE,and is stepped in a bearing, e',on the tower. The armv F of the vane is swiveled by its eye f on thet'ube- O, between the neck 2 of coupling A and the tower.

The wind-vane is not shown in the drawings, but it may have any approvedconstruction and be attached to the arm F in any approved way.

In a plug, d, fitted into the outer end of the 5o tube D, and in a plug,d', tted into the opposite neck, 4, of the cross-coupling A, there (Nomodel.)

is journaled the wind-wheel shaft G, to which is Iixed the hub or spiderII of the wind-wheel, and at the opposite end of the shaft is xed acrank-arm, I, to which is connected one end of a pitman, J, the otherend of which is attached to a crosshead,K,which is fitted to slide in aslotted standard or guide, L, fixed-in any approved way to the top ofthetube B, and to said cross-head K is attached the upper end of 6o thepump-rod M, which passes through the tubes B C, and is slotted ordivided into two parts or limbs, m m,which pass, respectively,

at opposite sides of the windmill-shaft and thence downward to connectwith the pump or other machine or gearing to be driven by. the mill. Abrace-rod, N, connected at one end to the vane-arm F, is pivoted or hungat its upper end on a pin, n, fixed to the crosshead standard L,andsupports the vane there- 7o from while allowing it to swing aroundfreely with the wind.

To the vane-arm F there are xed a couple of straps, O O, which haveslots forming guides, in which a bar, I), is fitted to slidefat the sideof the vane-arm, aand about at the center of the bar P there is pivotedat r one end of a rod, R, the other end of which is pivoted at r to anarm, s, which projects from a collar, S, attached to the mill-head,which 8o supports the wind-wheel, and it may be by screwing it onto theexterior threads of the tube D before the tube is screwed into thecross-coupling A. A chain, T, is attached at t to the end of the bar P,and thence runs under a guide sheave or pulley, U, journaled on thevane-arrn F, and thence passes upward to and over a guide sheave orpulley, V, journaled at the top of the cross-head guide L, and thencepasses downward through the 9o tubes and couplings B A C, as in Fig. l.A spiral spring, W, is attached to the lower end of the chain T, and tothis spring is connected a wire or rod, X, which extends down to or nearthe floor of the mill-tower within reach of an attendant. f

The operation is as follows: When the attendant draws the rod Xdownward, the chain e T will draw the bar I endwise toward themill-head, and thereby carry the rod R outroo ward and swing themill-head around with the wind-wheel shaft G about in line with the vaneon the arm F, and thus throw the mill into gear, and the rod X will befastened in any way by the attendant. The rod R acts as a brace or stayto prevent the wind-wheel from swinging too far around by contact of theend of rod R next its pivot r with the inner collar O, and as will beunderstood from Figs. 2 and 3 of the drawings. Should the wind blow toohard or in sudden gusts, the wheel will be blown around more or less inthe direction ofthe arrow l in Fig. 2, thereby forcing the rod R and barPoutward or backward and pulling on the chain T and expanding the springW incre or less, and the tension of the spring will cushion theresistance of the windl wheel and regulate its speed by holding more orless of the area of the wind-wheel sails to the Wind, the spring alsopreventing jar and shock of the parts of the mill. As the wind forcedecreases the wheel will gradually swing back again full face to thewind, as when first started.

To throw thc mill ont of gear, it only is necessary to unfasten the rodX and the wind will swing'the wheel around parallel with the vane as therod R and bar P are moved back ward, and, asindicated in dottedlines inFig. 2, the end of rod R next the pivot r then striking the outer collarO on the vane arm to prevent the wind-wheel from swinging againstthevane. It is evident that when the mill is out of gear no strain isbrought on the speed-regulating spring W, which then hangs loosely withthe chain Tand rod X consequently the elasticity of the spring will notbe impaired during such time.

The mill-head, made of wrought-iron crosscoupling A and tubes B OD, isless expensive to make and very much stronger than many styles ofcastiron heads, and with it a long wind-wheel shaft may be used, therebyfacilitating the easy, steady working of the mill and promoting itsdurability.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent` is 1. In a windmill, the 1nill-head made of a.wrought-metal tubular cross-coupling and tubes fitted therein,andadapted to receive the wind-wheel shaft and give passage for thepump-rod and gear pull chain or cord, slibstantially as shown anddescribed.

2. In a windmill, the niillhead made ofa wrought-metal tubular coupling,A, wroughtmetal tubes B CD, fitted therein, plugs dd', fitted,respectively, in the tube D and in the opposite neck 4 of the couplingA, the windwheel shaft G, journaled in said plugs d d', and said tube C,journaled and stepped in the niill tower, substantially as herein shownand described.

' 3. In a windmill, the combination of a head consisting of a tubularcrosscoupling,A, tubes B C D, fitted therein, plugs d d', fitted,repectively, in the tubes D and in the opposite neck 4 of coupling A,the wind-wheel shaft G, journaled in plugs d d, and said tube C,journaled and stepped in the mill-tower, a crank, I, on shaft G, aconnectingrod, J, a cross-head, K, connected to rod J, a guide, L ontube B for cross-head K, and a rod, M, connected to the cross-head andextending downward through the tubes and coupling B A C, substantiallyas set forth.

4. In a windmill, the combination, with a supporting-tower, as at E, anda head consisting of a tubular crosscoupling, A, metal tubesB C D,fitted therein, a shaft, G, journaled in plugs d d in the tube D andcoupling A, respectively, a crank, l", rod J, cross-head K, guide L, androd M, arranged substantially as specified, a vane-arm, F, pivoted ontube C between the neck 2 of coupling A and the tower E, and a brace, N,connected to arm F and hung pivotally to the top ofthe mill-head,substantially as herein shown and described.

5. In a windmill, the combination. with a supportingtower, a headjournaled therein, a wind-wheel journaled to the mill-head, and awind-vane hung to the head, of a bar,'1, fitted to slide on thevane-arm, an arm, as at s, on the mill-head near the wind-wheel, a rod,B, connecting the bar P and arm s, and a chain or cord, T, connected tothe bar Pand passed over guide-pulleys U V on the vane-arm andmill-head, respectively, and a pull-rod connected to chain T,substantially as herein set forth.

6. In a windmill, the combination, with a supporting-tower, a headjournaled thereon, awindwheel journaled on the mill-head, and awind-vanejournaled on thc head, of a bar, P, fitted to slide on the vane-arm, anarm, as at a, on the mil1-head near the wind-wheel, a rod, R, connectingthe bar I and arm s, a chain or cord, T, connected to the bar P, a
